Overview
The ZF 4143.216.024 BEVEL GEAR SET is a precision-engineered assembly designed to transfer rotational power at a right angle within the transmission’s differential or power take-off unit. This OEM genuine part, identified by SKU 4143.216.024, is a matched pair of spiral bevel gears that ensures smooth torque delivery and minimal backlash. It sits directly within the gear train of the HL 100 and HL 270 series housings, where it interfaces with the 4143101017 HOUSING and the 4143301039 HOUSING to maintain proper gear alignment and oil containment.
Symptoms of Failure
- Whining or howling noise during deceleration: Worn bevel gear teeth create a distinct high-pitched sound, often mistaken for wheel bearing noise. This is a common long-tail search query for “ZF transmission whine under load.”
- Vibration in the driveline at low speeds: As the gear set loses its factory lapped pattern, uneven tooth contact causes noticeable shuddering, especially during tight turns or when reversing.
- Metallic debris in the transmission oil: Flakes or silver particles found during an oil change indicate pitting or spalling on the bevel gear surfaces, requiring immediate replacement of the 4143.216.024 set.
- Backlash exceeding 0.5 mm: Excessive play between the bevel gears leads to clunking on acceleration and deceleration, often accompanied by oil seepage past the 0501318136 GASKET.

Compatibility
This bevel gear set is engineered for ZF WG series transmissions, specifically the WG100, WG130, and WG131 models. It is also a direct fit for the HL 100 and HL 270 series transfer cases. While primarily designed for these units, the 4143.216.024 may be used in WG180 and WG200 applications where the same gear ratio and housing dimensions are specified. Always verify the existing gear set part number before installation. The set requires proper shimming and torque of the 0636101084 CAP SCREW to secure the bearing preload.
